5y-x=10
Isolate the variable
add x to both sides
5y-x+x=10+x
5y=10+x
Divide both sides by 5
5y/5=10+x/5
y=2+1/5x
So y is equal to 2+1/5x
Ratio given 1:2
Let's suppose the ratio as x : 2x
Adding the ratio = 3x


40 and 80 are in the ratio 1:2 of 120.
Hope it helps!!!
I think its either A or D
Hope this helps!
0.27
so three divided by eleven is 0.27272727272727272727272727272727........so on and so forth.
If we simplify like terms on left and right sides we gwt
16x + 9 = 4x
Its B
